Unless you are in danger of being dropped by the coach, I would say to just go.
I mean, the expectations are low, there won't be any people she skates with making fun of her should she belly flop. This is just a great way to show family what she is doing, having the ice to herself (I am guessing) and her best outfit on.
I think this is a great way to break the ice for competition. Win, lose or draw, it will be the throw-away fun show.
Although I don't skate, I have to say I am amazed at the level of dependency I encounter (not skating specific, mind you).
Most of my family rode at some level of competition. There was never a coach on the sidelines, always 'only' a parent, my sister went 99% solo!
My son and I competed in martial arts with an organization not set up for coaching, nor was the format. bring what you got, hope you brought enough! It was a friendly atmosphere for most parts, and the learning opportunities were great. Especially in adversity, I might add! Heck, once I started competing, I did not even get to watch my kid, since our mats ran at the same time!
There is a point when the person with the wallet (parent, athlete) has to make it clear just who is paying the bills!
Since the event organizers will let you come without coach, I do believe this is meant to be!
